Have Transmission Questions? Ask a Mechanic for Answers ASAP
Good morning and welcome to JustAnswer!!!
When you place the shifter into neutral and then select 4WD what happens? Do you hear any clicking? Also do you know what codes are set?
The clicking is a sign something is wrong and it has set a DTC(Diagnostic Trouble Code) which we will need to have read to determine the cause..
Once you have the codes post them here so I can direct you to aa repair..
